Find the ratio of
(a) their areas and (b) their perimeters.
Answers
Answer:
AREA= 52 CM
PERIMETER = 40 CM
Step-by-step explanation:
Answer: 4:9
Step-by-step explanation:
a) Area of square with 4cm sides= 4cm square
= 16cm
Area of square with 6cm sides= 6cm square
= 36cm
Ratio of their area= 16:36
= simplify the number with 4
= 4:9 (ans)
b) Perimeter of square with 4cm sides= 4 X 4
= 16cm
Perimeter of square with 6cm sides= 6 X 6
= 24cm
Ratio of their perimeter= 16:24
= simplify the number with 4
= 4:6 (as it goes again, we will simplify the number with 2)
= 2:3 (ans)
